PROCESS OF MANUFACTURING: NE-IPIECE PACKING RINGS.

Application filed March 21, 1921. Serial No. 45 .51%.

To all whom it may concern:

Be it known that I, GEORGE W. OLNEY, a citizen of the United States,residing at Minneapolis, in the county of Hennepin, and

State of Minnesota, have invented certain new and useful Improvements inProcesses of Manufacturing One-Piece Packing Rings, of which thefollowing is a specification.

My invention relates to process of manufaoturing one piece split packingrings, and

an object is to provide a ring of this character which will be gas andsteam. tight. Heretofore in order to prevent leak in split packingrings, it has been customary to pro- 1 Vide a secondary or supplementarysplit ring which lies within the main ring, this inner ring having aspecial split which seals the split of the outer or main ring. A particular object, therefore, of my invention is to provide a one piece ring inwhich the split will be effectually sealed without the employment of thesupplementary ring. In this manner the process of manufacture is verymuch simplified, and the operation of the ring is more effective onaccount of not having two parts which may get out of adjustmentrelatively to each other.

The full objects and advantages of my invention will appear inconnection with the detailed description thereof, and the novel featuresembodied in my inventive idea will be particularly pointed out in theclaim.

In the accompanying drawings, Fig. l is a view in perspective of a blankring from which my improved split ring is manufactured. Fig. 2 is afragmentary view of the ring after it has been step-cut. Fig. 3 is afragmentary view of the ring after it has 4.0 been subjected to amilling operation at both of the step-cut ends. Fig. & is a fragmentaryView of the ring after a tongue has been welded to one of the step-cutends. Fig. 5 is a view in perspective of the tongue before it has beenwelded in place.

Referring to the drawings, the numeral 12 designates the body portion ofa ring having an internal annular flange 13 at one of its ends. Theblank ring can be produced in any suitable manner from tubing. Incarrying out my process, the blank ring shown in Fig. 1 is firstprovided with stepouts 14 and 16 as shown in Fig. 2 with the step cut 14extending through the body portion 12 of the ring and into the flangedportion 13 and with the stepcut 16 extending through the remainder ofthe flanged portion 13. The flanged portion 13 is then internally milledon both sides of the stepcut 14 to provide the cutout portions 18 and 20as shown in Fig. 3 whereby the flanged portion adjacent the stepcut A isenlarged to the diameter of the body portion 12. A tongue 22 of theproper size and shape to fill in the cutout portions 18 and 20 is weldedinto one of the cutout portions such as the portion 18 so that the freeend of this tongue extends into the other cutout portion such as 20 andis slidably positioned therein as shown in Fig. 4 from which figure itwill be apparent that this tongue is positioned above and adjacent thestepcut 16.

I claim:

The process of manufacturing one piece packing rings which consists inproviding a blank ring having an internal annular flange at one of itsends, step-cutting said ring so that one of the step cuts extendsthrough the body portion of the ring and into the flanged portionthereof and the other step out extends through the remainder of theflanged portion, internally milling said flanged portion on both sidesof the first mentioned step out to enlarge this portion to the diameterof the body portion of the ring, providing a tongue adapted to fill insaid milled out portion and welding said tongue atone end in said milledout portion whereby said tongue will be positioned above and adjacentthe second mentioned step out.

n testimony whereof I hereunto affix my signature.

GEORGE W. OLNEY
